JTRS will promote interoperability, streamline logistics across the Services, and reduce radio maintenance costs, through the development and fielding of software defined radios. The JTRS Joint Program Office (JPO) will oversee Service-led development and procurement of JTRS hardware and software, including the software-defined waveforms, which will define the functionality of these new radios. The new radios will match the size, weight, power, and interface requirements of legacy radio systems that they are designed to replace.
The SCA governs the structure and operation of the JTRS, enabling programmable radios to load waveforms, run applications, and be networked into an integrated system. For complete information on this key standard see the Software Communications Architecture Specifications, MSRC-5000SCA. The complete software specification along with Application Program Interface (API) and Security supplements can be downloaded from the JTRS website: http://jtrs.army.mil/sections/overview/fset_overview.html.
JTRS employs an evolutionary acquisition approach, which provides for multiple procurements with increasing capability and functionality over the life of the program. Rather than delay fielding until systems meet all requirements, initial capabilities are fielded as soon as possible, with new capabilities added as they mature. JTRS evolution can be viewed as three distinct phases: Near-Term, Mid-Term, and Long-Term.
Near-Term 2004-2007. This phase provides the warfighter with a foundation for future capabilities as JTRS compliant equipment is developed and fielded. During the near-term, JTRS will provide interoperability within each cluster and with all other clusters. Routing and retransmitting through dedicated JTRS nodes will provide interoperability with legacy radios and networks during the transition to full JTRS fielding.
Mid-Term 2007-2012. In the mid-term, tactical networks will use new JTRS capabilities, including the Wideband Networking Waveform (WNW) and enhanced network, spectrum and security management. Mid-term JTRS will also provide route and retransmission between JTRS and legacy networks.
Long-Term 2012-2030. Over the long-term, JTRS will provide a fully integrated information system network to include active and passive information operations management across the joint and combined environments. The system will include a self-establishing and self-healing "smart" network, which will automatically manage the RF domain.

JTRS Groupings. Service acquisition requirements for JTRS are grouped according to similarity of requirements and fielding schedules. These groups are currently referred to as “clusters.” Of special interest to the UA community are Cluster 1 and Cluster AMF, which provide airborne secure voice and data communications.
.
Cluster 1. Provides a multi-channel software programmable, hardware-configurable digital radio networking system, and supports requirements from the Army Aviation Rotary Wing, Air Force Tactical Control Party (TACP), and Army and USMC Ground Vehicular platforms. In FY07, the Navy will begin fielding an SCA compliant CDL (TCDL), using a JTRS Cluster 1 terminal equipped with a high-band module.
